NFT is only a name, a technology, a tool, a new invention of human civilization. We need to know this fact and should not over rate NFT. Whatever technology, it only is able to exist and grow of if it has real use cases and utility. Without use cases and utitlity or has it with bad quality, people will feel no reason to use it.
Rollbot NFT is developed by Rollbit casino that is already a big casino with lot of games and products. So I am sure Rollbot will be given more use cases and utility by the casino. It is internal but if the casino can expand use cases and utility to external platforms, that will be massive.
Their NFT is not just some sort of jpeg that are popular these days who have no usecase and only hyped by their community. You can check
here the utility of their NFTs and as you can see on their roadmap they plan to add more in the future which owners can benefit from using their platform. They even plan to add a pvp type of game exclusive for their holders. You can also get a share of profit from their themed-games if you are a NFT holder.
